Amsoil vs. Redline

Hi, guys! This shouldn't be too controversial a question (yeah, right!), but do you believe that Amsoil Series 2K 0W-30/3K 5W-30 and Redline 5W-30/10W-30 are fairly comparable oils in terms of quality? I've been reading the posts here for a while, and it seems like Amsoil gets more attention; particularly when it comes to ragging on their marketing practices. Anyway, I have a turbo-charged 4-banger that is going to be receiving some serious performance mods in the future. Performance AND protection are crucial. Thanks!

Bashing Amsoil's marketing is a favorite past time around here, it seems. I would actually give the edge in wear protection to Amsoil over Redline. Most of the Redline results have hardly been spectacular, especially for something that costs $8.95/quart. The notable exception would be the results that someone posted from their 5W-40 that sprintman mentioned. Maximum performance seems to be Redline's niche, so depending on which you wanted more would determine which brand was for you. My prediction: There will be 30 replies here by morning [Big Grin]

I guess everyone was sleeping, as there were no more replies overnight! [Smile] We haven't seen enough Redline analysis reports on here to say that Amsoil is better or Redline is better. I do believe Redline is designed more for hard driving in mind though, while Amsoil tries to gear their oil for longer intervals.

I wouldn't go into a US vs. Them catagory, as I really think you are splitting hairs. My vote would go to whichever you can find the easiest/cheapest. Also I wouldn't hesitate to through the Amsoil 10w30 ATM in the mix if you are looking for something a little less expensive. It is especially developed for turbo applications. Though if it were mine I would use the Series 2000 0w30. Anyhow good luck.

I use the Amsoil 10W30 in a twin turbo and it does fine via analysis. However, short drains as I use 5000 miles or one year. If this is a manual transmission I highly recommed the RedLine gear oils over Amsoil especially in cold weather shifting.

I think that Subaru still recommends 5w-40 or 10w-40 grades for "Severe Service" use, so I'd start with either the Amsoil 10w-40 or this new Redline 5w-40. I have quite a bit of experience with the Amsoil product in turbocharged VW's and it holds up very well. Recent oil analyses of the Redline 5w-40 have been impressive as well .... If anyone has a spec sheet on the new Redline 5w-40, please e-mail me a copy at [email protected] .... TooSlick

Not what you asked about but if your car recommends a 5W40 synthetic consider Mobil Delvac 1. It is a fine oil at a reasonable price.

I contacted Red Line and received the following response: Q: Do you carry an SAE 5W-40 version of your engine oil? A: Yes, Red Line makes a 5W40 street engine oil. Q: Must be new since no info on your web site? A: The 5W40 has been available for about 6 months but isn't listed on the web site. I requested a PDF version of their spec sheet and got one. Here's the pertinent info: API Service Class = SL/SJ/SH/CD/CF (Gas/Diesel) Viscosity Grade SAE = 5W-40 Vis @ 100C, cSt = 15.1 Vis @ 40C, cSt = 94 Viscosity Index = 170 CCS Viscosity, Poise = 55 @ -30C HTHS Vis, cP @ 150C = 4.6 Pour Point, C = -45 Pour Point, F = -49 Flash Point, C = 250 Flash Point, F = 480 NOACK Evaporation Loss, 1 hr @ 482F (250C), % = 6 I can send anyone the pdf if they want it. By the way, this spec sheet also lists a 5W-20 oil as well.
